摘　　要：置换定理是"电路"课程的一个基本定理,它既是电路分析的工具,也是其它电路定理的理论基础。本文讨论置换定理的成立条件,指出电路具有惟一解是应用置换定理的充分条件,而不是必要条件。对具有非惟一解的电路应用置换定理进行了讨论。本文的分析结果可供讲授"电路"课程的教师参考。Substitution theorem is a fundamental theorem in Circuit course.It gives theoretical basis for other circuit theorems and can be applied to analyze circuits.This paper has discussed establishment condition of the theorem which is described as uniqueness of circuit solution in textbooks.It concludes that uniqueness of circuit solution is a sufficient condition but not a necessary condition for application of substitution theorem.Application of the theorem on circuits which have non-unique solutions is also discussed.

关 键 词：置换定理 电路的解 电路分析
